Nola transwallacea sp. n.


Nola transwallacea

7-8mm. The male antennae are bipectinate over the basal section. There is some sexual dimorphism in forewing pattern, females having a more extensively pale and yellowish medial area. Outside this, the forewings are traversed by a series of diffuse, slightly zig-zag brown fasciae that are mostly clearly defined at the distal margin, where the postmedial and submarginal are both indicated by a sharp boundary between dark brown and pale fawn. The hindwings are grey-brown, distinctly darker than the medial area. The male genitalia (Seram specimen) and abdomen suggest a relationship to spinivesica. The eighth sternite has apodemes closely associated at the centre as in spinivesica, but those of the tergite form part of a much longer, catapult-like structure. The valve bases are somewhat expanded and invested with long hairs as in spinivesica, and the ventral arm is much narrower than the dorsal one, but tapers to an apical spur rather than being rounded, and the harpe is smaller, more spine-like. The aedeagus vesica has a triangular sclerite with coarse spines along the edge rather than a scattering of small spines throughout. The female genitalia are as illustrated, with two signa, one much larger than the other.
